The dispersion mechanism 70 includes a columnar body 71 disposed in a direction crossing the packaging bag 27, and a plurality of columns 71 disposed upstream of the columnar body 71 in the transport direction and pressed against the first surface 27 </ b> A of the packaging bag 27. The 1st press member 72 and the some 2nd press member 73 which are arrange | positioned in the conveyance direction downstream with respect to the columnar body 71, and are pressed by the 1st surface 27A of the packaging bag 27 are provided. The dispersion mechanism 70 is disposed in the conveyance path 62 that conveys the packaging bag. In the present embodiment, a plurality of the first pressing members 72 and the second pressing members 73 are arranged, but one or more of the first pressing members 72 and the second pressing members 73 may be arranged.

  The terms “upstream” and “downstream” are terms used in the transport direction F of the sachet, and “downstream” when opposite to the transport direction F when positioned on the transport direction side with respect to a certain reference. The case located on the side is defined as “upstream”.

  In the present embodiment, the columnar body 71 has a cylindrical shape. The cross-sectional shape perpendicular to the length direction of the columnar body 71 may be a closed curve such as an ellipse or a polygon such as a triangle or a quadrangle. The size of the cross-sectional shape perpendicular to the length direction of the columnar body 71 is appropriately determined according to the size of the medicine 25 packaged in the packaging bag 27. In the present embodiment, the columnar body 71 is disposed at a position perpendicular to the transport direction F.

  It is preferable that the length of the columnar body 71 is longer than the width of the packaging bag 27 that passes through the conveyance path 62.

  In the present embodiment, the first pressing member 72 and the second pressing member 73 have the same structure. Based on the 2nd press member 73, the structure is demonstrated. The second pressing member 73 is a pair of second wheels 73A that are pressed against the first surface 27A of the packaging bag 27, a second axle 73B that supports the second wheels 73A, and a second axle 73B that rotatably supports the second wheels 73A. The second frame 73C and a second fixture 73E that rotatably supports the second shaft 73D of the second frame 73C. In the present embodiment, the second frame 73C including the second wheels 73A is formed on the first surface of the packaging bag 27 (not shown) by the second spring 73F that is the second urging member provided on the second fixing tool 73E. 27A is energized. In the present embodiment, the second pressing member 73 is pressed against the first surface 27A of the packaging bag 27 by the second spring 73F, which is an urging member, but the present invention is not limited to this. For example, the second pressing member 73 can be pressed against the first surface 27A of the packaging bag 27 by gravity.

  As with the second pressing member 73, the first pressing member 72 includes a first wheel 72A that is pressed against the first surface 27A of the packaging bag 27, a first axle 72B that supports the first wheel 72A, and a first A pair of first frames 72C that support the axle 72B, a first fixture 72E that rotatably supports the first shaft 72D of the first frame 72C, and a first urging member provided on the first fixture 72E. A first spring 72F. The wheel (the first wheel 72A and the second wheel 73A) means a member that rotates around an axis, and its shape is not limited as long as it can rotate.

  It is preferable that the angle (toe angle) with respect to the conveyance direction F of the second wheel 73A is, for example, 15 ° to 30 °. When the second wheel 73A and the transport direction F are parallel, the toe angle is 0 °, and when the second wheel 73A and the transport direction F are orthogonal, the toe angle is 90 °.

  The toe angles of the second wheels 73A of the second pressing members 73 can be the same in the same direction, and can be different from each other.

  The second wheel 73A of the second pressing member 73 is disposed by the second spring 73F so that the lower end of the second wheel 73A is positioned at the lowest point, and the lower end of the second wheel 73A is placed in the packaging bag 27 at the lowest point. It arrange | positions in the position which contacts the packaged chemical | medical agent 25. FIG.

  Since the second shaft 73D of the second frame 73C is rotatably supported by the second fixture 73E, the second wheel 73A moves away from the conveyance path 62 against the urging force of the second spring 73F. It is configured to be possible. The second wheels 73A of the second pressing members 73 are configured to be independently movable in the direction opposite to the pressing direction.

  Since the second wheel 73A is urged by the second spring 73F, when the second wheel 73A passes the medicine 25, the second wheel 73A is moved in the pressing direction by resisting the urging force of the second spring 73F. It is possible to move in the opposite direction, get over the drug 25, and avoid damage to the drug 25. Since the direction of the second wheel 73A, that is, the toe angle is fixed, when the second wheel 73A passes through the medicine 25, the orientation of the medicine 25 can be changed by being packaged in the packaging bag 27. .

  As described above, the second pressing member 73 and the first pressing member 72 have the same configuration. However, as shown in the present embodiment, the number of the first pressing members 72 (four) and the number of the second pressing members 73 (three) can be made different, and can be the same.

  The direction and toe angle of the first wheel 72A of the first pressing member 72 and the second wheel 73A of the second pressing member 73 can be determined as appropriate. In the present embodiment, the first wheel 72A and the second wheel 73A are inclined in different directions with respect to the transport direction F, but the present invention is not limited to this.

  The pressing member (including the first pressing member 72 and the second pressing member 73) is a member that is inclined with respect to the transport direction F of the transport path, and is in a position where it can come into contact with the medicine in the packaging bag. It means a member that is arranged. Therefore, the shape of the inclined member is not particularly limited.

  Next, the operation of the first distribution mechanism 70 will be described based on FIGS.

  As shown in FIG. 3, the dispersion mechanism 70 is on standby in the conveyance path 62 at a position downstream of the imaging position. A packaging bag 27 for packaging the medicine 25 is transported on the transport path 62 along the transport direction F. The packaging bag 27 is temporarily stopped at the imaging position. The waiting dispersion mechanism 70 is configured to be able to reciprocate for one package with respect to the package bag 27 stopped at the imaging position. In the embodiment, the movement of the dispersion mechanism 70 in the standby position is defined as the forward movement, and the movement of the distribution mechanism 70 to the standby position after the forward movement is defined as the backward movement.

  The first pressing member 72 and the second pressing member 73 of the dispersion mechanism 70 are arranged on the first surface 27 </ b> A side of the packaging bag 27. The columnar body 71 of the dispersion mechanism 70 is disposed between the second surface 27 </ b> B of the packaging bag 27 and the conveyance path 62. In the present embodiment, as described above, the first surface 27A of the sachet 27 means the opposite side to the surface of the sachet 27 placed on the conveyance path 62, and the second surface 27B of the sachet 27 The term “surface” refers to the surface of the packaging bag 27 placed on the conveyance path 62. The relative positions of the first pressing member 72, the second pressing member 73, and the columnar body 71 that constitute the dispersion mechanism 70 are fixed. Therefore, the first pressing member 72, the second pressing member 73, and the columnar body 71 can move upstream and downstream with respect to the transport direction F while maintaining a predetermined distance. Furthermore, the first pressing member 72 and the second pressing member 73 are pressed against the first surface 27 </ b> A of the packaging bag 27.

  Therefore, by moving the dispersion mechanism 70 in the transport direction F, the swell 90 can be forcibly generated in the sachet 27, and the swell 90 can be moved.

  Since the first pressing member 72 and the second pressing member 73 are pressed against the first surface 27A, the movement of the packaging bag 27 can be restricted to some extent, and tension can be applied to the packaging bag 27.

  In the present embodiment, the lower ends of the first wheel 72 </ b> A and the second wheel 73 </ b> A are at a position lower than the upper end of the columnar body 71 with the conveyance path 62 as a reference. By setting the first wheel 72A, the second wheel 73A, and the columnar body 71 to such a positional relationship, tension can be applied to the packaging bag 27 by the first wheel 72A and the second wheel 73A. Since the packaging bag 27 is pressed by the lower end of the first wheel 72A and the second wheel 73A, the movement of the packaging bag 27 can be regulated.

  The conveyance path 62 includes a drive unit (not shown) for conveying the packaging bag 27. Examples of the drive unit include a pair of nip rollers that sandwich the first surface 27A and the second surface 27B of the packaging bag 27, and a motor that rotationally drives the pair of nip rollers. The pair of nip rollers can apply tension to the packaging bag 27. By changing the rotation direction of the motor, the packaging bag 27 can be conveyed in both the upstream side and the downstream side.

  As shown in FIG. 4, the dispersion mechanism 70 in the standby state is moved upstream. The swell 90 is moved by moving the columnar body 71 upstream along the first surface 27A of the packaging bag 27 while holding the packaging bag 27 by the first pressing member 72 and the second pressing member 73. The overlapping of the medicines 25 in the sachet 27 can be eliminated, or the posture of the medicine 25 standing in the sachet 27 is laid down in a stable state, that is, the medicine 25 is efficiently spread. It becomes possible.

  When the columnar body 71 passes, the movement of the packaging bag 27 is restricted by the first pressing member 72 and the second pressing member 73 and tension is applied to the packaging bag 27, so that the medicine 25 is easily spread. Presumed to be in a state.

  As described above, the plurality of first pressing members 72 and the second pressing member 73 are independently movable upward. Accordingly, even when the size of the passing medicine 25 is different in the width direction of the transport direction F, each of the first pressing member 72 and the second pressing member 73 can spread the medicine 25 without being affected by it. It becomes possible. That is, since the first pressing member 72 and the second pressing member 73 can move independently, it is possible to press the smallest medicine 25 while pressing the largest medicine 25.

  In the present embodiment, the first pressing member 72 is inclined with respect to the transport direction F as shown in FIG. When moving the dispersion mechanism 70 in the standby state to the upstream side, the direction of the medicine 25 is preferably inclined with respect to the transport direction F by the first pressing member 72. By changing the direction of the medicine 25, the medicine 25 can be easily spread by the swell 90. However, the first pressing member 72 is not necessarily inclined with respect to the transport direction F.

  As shown in FIG. 5, the dispersion mechanism 70 that has moved the distance of one package to the upstream side is moved backward by the distance of one package for the downstream side, and the dispersion mechanism 70 returns to the standby position. . As described in FIG. 4, when the dispersion mechanism 70 is moved downstream, the dispersion mechanism 70 can forcibly generate the undulation 90 in the packaging bag 27, and the undulation 90 is moved. Can do.

  Since the first pressing member 72 and the second pressing member 73 are pressed against the first surface 27A, the movement of the packaging bag 27 can be restricted to some extent, and tension can be applied to the packaging bag 27. By holding the packaging bag 27 by the first pressing member 72 and the second pressing member 73 and moving the columnar body 71 downstream along the first surface 27A of the packaging bag 27, the medicine can be efficiently used. 25 can be spread.

  Since the second pressing member 73 is inclined with respect to the transport direction F, the direction of the medicine 25 can be tilted with respect to the transport direction F by the second pressing member 73. In addition, the dispersion mechanism 70 can be reciprocated a plurality of times as necessary. The dispersion mechanism 70 is mechanically connected to a driving device (not shown). The operation of this drive device is controlled by a drive control unit provided in the inspection apparatus main body 33.

  Moreover, the packaging bag 27 can be made into the loosened state by controlling a drive part (not shown). In some cases, the medicine 25 can be spread more reliably by being dispersed by the dispersion mechanism 70 while the sachet 27 is loosened. If the tension of the packaging bag 27 is too strong, it is estimated that the movement of the medicine 25 is restricted and it may be difficult to spread.

  In the present embodiment, the mode in which the dispersion mechanism 70 is reciprocated with respect to the stopped sachet 27 has been described. However, the dispersion mechanism 70 can be fixed and the sachet 27 can be reciprocated. That is, it is only necessary that the dispersion mechanism 70 and the packaging bag 27 are relatively movable.

  While the dispersion mechanism 70 reciprocates, the forward movement speed of the dispersion mechanism 70 and the backward movement speed of the dispersion mechanism 70 may be different. The dispersion mechanism 70 is intended to eliminate overlapping of the medicines 25 in the packaging bag 27 and to lay down the standing medicine 25 in the packaging bag 27. It is preferable to vary the moving speed of the dispersion mechanism 70 in accordance with each purpose. For example, in order to eliminate the overlap of the medicines 25, it is necessary to apply a relatively strong force to the medicines 25, and it is preferable that the moving speed of the dispersion mechanism 70 is fast. Further, when the standing medicine 25 is laid down, if a relatively strong force is applied to the medicine 25, there is a concern that the medicine 25 does not lie down and gets over the columnar body 71, and the moving speed of the dispersion mechanism 70 is preferably slow. . Here, whether the moving speed is fast or slow is determined based on the case where the moving speeds according to the above-described purposes are compared. When the slow movement speed is set to 1, for example, the high movement speed is preferably 3 or more and 7 or less.

  In accordance with the above-described purpose, for example, the moving speed of the forward movement of the dispersion mechanism 70 can be reduced and the moving speed of the backward movement can be increased. Moreover, the moving speed of the forward movement of the dispersion mechanism 70 can be increased, and the moving speed of the backward movement can be decreased.

  Since it is preferable that the medicine 25 is laid down before imaging the medicine 25, overlapping of the medicines 25 is eliminated by increasing the moving speed of the forward movement of the dispersion mechanism 70, and then the moving speed of the backward movement It is preferable to lay the drug 25 on its side by slowing down.

  Next, when the dispersion mechanism 70 reciprocates a plurality of times, the movement speed of the dispersion mechanism 70 includes the following modes. If the dispersion mechanism 70 reciprocates three times, the moving speed of the forward movement and the backward movement of the dispersion mechanism 70 can be the same for the three reciprocations. Further, the movement speed of the second reciprocation and the third forward movement can be made the same, and the movement speed of the third backward movement can be made slower than the other movement speeds. The overlapping of the medicines 25 can be eliminated, and the medicine 25 can be laid down. However, the reciprocating movement of the dispersion mechanism 70 can be appropriately changed according to the purpose.

  The distribution mechanism 70 is not limited to the configuration of the present embodiment. FIG. 6 is a configuration diagram of the second distribution mechanism 80 provided in the dispensing inspection device 20. The dispersing mechanism 80 is a columnar body 81 arranged in a direction crossing the packaging bag 27 (not shown), and is disposed upstream of the columnar body 81 in the transport direction, and the first surface of the packaging bag 27 (not shown). A plurality of first pressing members 82 pressed by 27A and a plurality of second pressings pressed on the first surface 27A of the unillustrated sachet 27 disposed downstream of the columnar body 81 in the transport direction. And a member 83.

  The dispersion mechanism 80 is disposed in the conveyance path 62 that conveys the packaging bag. In the present embodiment, a plurality of first pressing members 82 and a plurality of second pressing members 83 are arranged, but one or more of the first pressing members 82 and the second pressing members 83 may be arranged.

  In the present embodiment, the first pressing member 82 and the second pressing member 83 have the same structure. Based on the 2nd press member 83, the structure is demonstrated. The second pressing member 83 includes a second tip member 83A pressed against a first surface 27A (not shown) of the packaging bag 27, a second shaft 83B fixed to the second tip member 83A, and a second shaft 83B. A second coil spring 83C attached to the second shaft 83B, a second ring 83D for retaining the second shaft 83B on the opposite side of the second tip member 83A, and a second bracket 83E formed with a through hole. And a second sleeve 83F disposed in the through hole. In the present embodiment, a plurality of second shafts 83B are inserted through a common second bracket 83E. The second sleeve 83F is made of resin and facilitates the movement of the second shaft 83B.

  The second tip member 83A is biased by a second coil spring 83C that is a biasing member supported by the second bracket 83E, and the second tip member 83A presses the first surface 27A (not shown) of the packaging bag 27. . Note that the second tip member 83A may be pressed against the first surface 27A (not shown) of the packaging bag 27 by gravity without providing the second coil spring 83C.

  Since the second ring 83D is larger than the through hole of the second bracket 83E, the second shaft 83B is prevented from coming off from the second bracket 83E.

  Similarly to the second pressing member 83, the first pressing member 82 is a first tip member 82A pressed against a first surface 27A (not shown) of the packaging bag 27, and a first tip member 82A fixed to the first tip member 82A. A first shaft 82B, a first coil spring 82C that is elastically attached to the first shaft 82B, a first ring 82D for retaining that is attached to the opposite side of the first tip member 82A of the first shaft 82B, and a through hole A first bracket 82E having a hole and a first sleeve 82F disposed in the through hole are provided. In the present embodiment, a plurality of first shafts 82B are inserted through a common first bracket 82E.

  The first tip member 82 </ b> A and the second tip member 83 </ b> A have a conical shape that tapers toward the conveyance path 62, and the tip of the conical shape is formed in a curved surface shape. The apex angles of the first tip member 82A and the second tip member 83A are preferably 60 ° to 120 °, for example.

  The relative positions of the first pressing member 82, the second pressing member 83, and the columnar body 81 that constitute the dispersion mechanism 80 are fixed. Therefore, the first pressing member 82, the second pressing member 83, and the columnar body 81 can move upstream and downstream with respect to the transport direction F while maintaining a predetermined distance. Furthermore, the first pressing member 82 and the second pressing member 83 are pressed against the first surface 27A (not shown) of the packaging bag 27.

  Note that the relative positions of the first pressing member 82, the second pressing member 83, and the columnar body 81 only need to be fixed during movement for spreading the medicine 25. Therefore, before the medicine 25 is spread, the relative positions of the first pressing member 82, the second pressing member 83, and the columnar body 81 can be appropriately changed according to the size of the medicine 25 to be spread. .

  Therefore, by moving the dispersion mechanism 80 in the transport direction F, the swell 90 (not shown) can be forcibly generated in the sachet 27, and the swell 90 can be moved. Since the first pressing member 82 and the second pressing member 83 are pressed against the first surface 27A, the movement of the packaging bag 27 can be restricted to some extent, and tension can be applied to the packaging bag 27.

  As a result, the medicine 25 packaged in the packaging bag 27 by the undulation 90 can be effectively spread.

  The first tip member 82A is biased by the first coil spring 82C, and the second tip member 83A is biased by the second coil spring 83C. When the first tip member 82A and the second tip member 83A pass the medicine 25 (not shown), the first tip member 82A, by resisting the urging force of the first coil spring 82C and the second coil spring 83C, Further, the second tip member 83A moves in the direction opposite to the pressing direction and can get over the medicine 25, and the medicine 25 can be prevented from being damaged.

  Note that when the first tip member 82A and the second tip member 83A pass through the medicine 25, the orientation of the medicine 25 can be changed by being wrapped in the packaging bag 27 by the conical inclined surface or the curved surface of the tip. it can. By changing the direction of the medicine 25, the medicine 25 can be easily spread. However, the first tip member 82A and the second tip member 83A are not limited to a conical shape.

  Furthermore, a plate-like member can be applied as the first pressing member and the second pressing member constituting the dispersion mechanism. By using a plate-like member, the structure can be simplified.

  FIG. 7 is a configuration diagram of a modified example of the second distribution mechanism 80 provided in the dispensing inspection device 20. As shown in FIG. 7, the second dispersion mechanism 80 includes a spiral columnar body 85 instead of the columnar body 81. The spiral columnar body 85 includes a columnar body 85A and a spiral blade 85B provided on the outer peripheral surface of the columnar body 85A. A spiral groove 85C exists on the outer peripheral surface of the columnar body 85A due to the spiral blade 85B.

  The spiral columnar body 85 is connected to a drive unit (not shown) and can rotate in the same direction as the transport direction F or in the opposite direction. The spiral columnar body 85 can rotate independently of the movement of the dispersion mechanism 80. While the dispersion mechanism 80 moves, the spiral columnar body 85 can promote the lying down of the standing medicine 25.

  FIG. 8 is an explanatory diagram for explaining the operation of the spiral columnar body 85. As shown in FIG. 8, by moving a dispersion mechanism 80 (not shown), the spiral columnar body 85 passes between the packaging bag 27 and the conveyance path 62. At that time, the plurality of medicines 25 packaged in the packaging bag 27 gets over the spiral columnar body 85. Since the spiral columnar body 85 is rotating, the medicine 25 receives a force parallel to the axial direction of the columnar body 85A by the spiral blade 85B. As a result, the spiral columnar body 85 can promote the lying down of the medicine 25.

  The crest diameter CD, the trough diameter RD, the pitch P, and the rotation speed of the spiral columnar body 85 are appropriately determined in consideration of the size of the medicine 25 to be laid down. By adjusting the difference between the peak diameter CD and the valley diameter RD, it is possible to apply a force that easily breaks the balance of the standing drug 25.

  The pitch P defines the width of the spiral groove 85C. The size of the pitch P is determined so that the standing medicine 25 can enter the spiral groove 85C. In the embodiment, since the packaging bag 27 is pressed by the first pressing member 82 and the second pressing member 83 (not shown) on the upstream side and the downstream side of the spiral columnar body 85, the packaging bag 27 imparts tension. Has been. The standing medicine 25 receives a larger force from the packing bag 27 toward the spiral columnar body 85 as compared with the standing medicine 25. As a result, the standing medicine 25 can easily enter the spiral groove 85C. The medicine 25 that has entered the spiral groove 85C comes into contact with the rotating spiral blade 85B. As a result, the standing medicine 25 is self-selected and easily laid down by the spiral columnar body 85.

  The rotational speed of the spiral columnar body 85 is preferably set to a rotational speed at which the spiral blade 85B can contact the drug 25 within the time required for the drug 25 to get over the spiral columnar body 85. This is to make the medicine 25 fall more reliably.

  Therefore, by slowing down the moving speed of the dispersion mechanism 80, the time required for the medicine 25 to get over the spiral columnar body 85 is lengthened, and by increasing the rotational speed of the spiral columnar body 85, the spiral blade 85B and Contact with the medicine 25 becomes more reliable.

  Also in the second dispersion mechanism 80, as in the first dispersion mechanism 70, the moving speed of the forward movement and the moving speed of the backward movement are determined according to the purpose.

  FIG. 9 is a configuration diagram of the third distribution mechanism 100 provided in the dispensing inspection device 20. The dispersing mechanism 100 is a columnar body 101 arranged in a direction crossing the packaging bag 27 (not shown), and is disposed upstream of the columnar body 101 in the transport direction, and the first surface of the packaging bag 27 (not shown). A plurality of first pressing members 102 pressed by 27A and a plurality of second pressings pressed on the first surface 27A of the unillustrated sachet 27 disposed downstream of the columnar body 81 in the transport direction. Member 103.

  In the present embodiment, a plurality of first pressing members 102 and a plurality of second pressing members 103 are arranged, but one or more of the first pressing members 102 and the second pressing members 103 may be arranged.

  In the present embodiment, the first pressing member 102 and the second pressing member 103 have the same structure. Based on the 2nd press member 103, the structure is demonstrated. The second pressing member 103 includes a second plate member 103A that is pressed by a first surface 27A (not shown) of the packaging bag 27, and a second shaft portion 103B that movably supports the second plate member 103A. A second frame 103C that rotatably supports the second shaft portion 103B, and a second torsion coil spring 103D that urges the second plate-like member 103A toward the first surface 27A. The second plate-like member 103A can be moved independently by being urged by the second torsion coil spring 103D.

  The second plate-like member 103A is preferably a material that does not damage the packaging bag 27 (not shown). For example, it is preferably composed of polyoxymethylene (POM).

  As described above, the first pressing member 102 supports the first plate member 102A, the first shaft portion 102B that movably supports the first plate member 102A, and the first shaft portion 102B so as to be rotatable. A first frame 102C and a first torsion coil spring 102D that urges the first plate member 102A toward the first surface 27A are provided.

  In the third dispersion mechanism 100 as well, like the first dispersion mechanism 70, the moving speed of the forward movement and the moving speed of the backward movement are determined according to the purpose. Further, also in the first dispersion mechanism 70 and the third dispersion mechanism 100, the spiral columnar body 85 applied to the second dispersion mechanism 80 is applied according to the purpose.

[Configuration of dispensing inspection device]
FIG. 10 is a block diagram showing an electrical configuration of the inspection apparatus main body 33 of the dispensing inspection apparatus 20. The inspection apparatus main body 33 includes an input drug type information acquisition unit 40, a drug information database (hereinafter abbreviated as a drug information DB) 41, an input drug type correct / incorrect determination unit 42, and a drug appearance database (hereinafter abbreviated as a drug appearance DB). 43, a distinct appearance number information acquisition unit 44, a distinction count unit 45, an appearance distinction number correct / incorrect acquisition unit 46, a mixability determination possibility determination unit 47, a packaging correctness determination unit 48, a communication interface (dispensing information) Acquisition unit) 49.

  The input drug type information acquisition unit 40 constitutes an input drug type information acquisition unit together with the third camera 31. The input drug type information acquisition unit 40 uses, for example, at least barcodes and characters recorded in the package 36 as the drug type information 37 from the image data (including barcode reading information) of the drug type information 37 input from the third camera 31. Extract one. Then, the input drug type information acquisition unit 40 outputs the drug type information 37 to the input drug type correctness determination unit 42. The input drug type information acquisition unit 40 may be provided in the third camera 31 instead of being provided in the inspection apparatus main body 33.

  FIG. 11 is an explanatory diagram for explaining the correctness / incorrectness determination process by the input drug type correctness / incorrectness determination unit. As shown in FIG. 11, in the drug information DB 41, the drug type of the drug 25, the drug type information 37, and the generic drug information indicating the correspondence between the generic drug and the generic drug (generic drug) are stored in advance in association with each other. ing. “A, A1, A2,..., B, B1, B2,..., C, C1, C2,...” Described in the drug type column in the figure indicate the drug type of the drug 25. Yes. The drugs A1 and A2 are generic drugs of the drug A, the drugs B1 and B2 are generic drugs of the drug B, and the drugs C1 and C2 are generic drugs of the drug C. Hereinafter, when described as the drug 25, all drug types are included, and when described as the drugs A, B,..., The drug types are indicated.

  In the “medicine identification information” column in the figure, drug type information 37 of the package 36 is recorded. In the “generic drug information” column, when the drug 25 is a generic drug, the drug type (or drug type information 37) of the original drug is recorded. By referring to the drug information DB 41, the drug type of the drug 25 is clarified from the drug type information 37, and further, it is possible to determine the original drug or the generic drug (drug having the same active ingredient) of the drug 25.

  The input drug type correctness determination unit 42 refers to the drug information DB 41 based on the dispensing information 22 input from the receipt computer 18 via the communication interface 49 and the drug type information 37 input from the input drug type information acquisition unit 40. The correctness / incorrectness of the drug type of the medicine 25 put in the packaging machine 26 is determined.

  Specifically, the input drug type correct / incorrect determination unit 42 determines the drug type of the drug 25 to be input into the packaging machine 26 based on the dispensing information 22. Further, the input drug type correctness / incorrectness determination unit 42 refers to the drug information DB 41 based on the drug type information 37 and stores the drug 25 picked in the picking operation 12 and input to the packaging machine 26 (indicated as input drug in the figure). Determine the drug type. Then, the input drug type correct / incorrect determination unit 42 collates the drug type of the drug 25 specified in the dispensing information 22 with the drug type of the drug 25 to be input to the packaging machine 26 to thereby determine the drug to be input to the packaging machine 26. The correctness of 25 drug types is determined. The inserted drug type correctness / incorrectness determination unit 42 determines that the drug type of each drug 25 that is input to the packaging machine 26 matches the drug type of the drug 25 specified in the dispensing information 22 is correct. Judge that it is wrong.

  At this time, the input drug type correctness / incorrectness determination unit 42 is a case where the drug 25 corresponding to the drug type information 37 is a generic drug (or an original drug is acceptable) having the same active ingredient as the drug 25 specified by the dispensing information 22 The drug type is determined to be correct even if the drug types do not match. Note that the input drug type correctness / incorrectness determination unit 42 is a same-type same-effect drug having the same active ingredient even if the drug 25 corresponding to the drug type information 37 is not a generic drug of the drug 25 specified by the dispensing information 22. If so, determine that the drug type is correct. In this case, information indicating the correspondence relationship between the same-type same-effect drugs is stored in advance in the drug information DB 41.

  When it is determined that the medicine type of the medicine 25 to be inserted into the packaging machine 26 is incorrect, the input medicine type correctness / incorrectness determination section 42 outputs a determination result J1 including information on the corresponding medicine type to the display section 34. Thereby, the display part 34 displays that the chemical | medical agent type of the chemical | medical agent 25 thrown into the packaging machine 26 is incorrect, and its chemical | medical agent type. For example, when drug type information 37 of a package 36 of a drug 25 (here, drug E) that is not specified in the dispensing information 22 is imaged by the third camera 31, the input drug type correct / incorrect determination unit 42 displays the drug “drug”. A determination result J1 indicating that “E” is incorrect is output. Then, the display unit 34 displays, for example, warning information “Drug E is picked incorrectly”. In addition, you may change the display mode of this warning display suitably.

  Returning to FIG. 10, the input drug type correctness determination unit 42 is provided with a packaged drug information acquisition unit 50. The packaging medicine information acquisition unit 50 refers to the medicine information DB 41 based on the dispensing information 22 and the medicine type information 37 of each picked medicine 25, and each packaging bag 27 (packaging 1 , Package 2,...), The packaged drug information 51 indicating the drug type of the drug 25 to be packaged and the number of each drug type is obtained (see FIG. 12). The packaged medicine information acquisition unit 50 outputs the packaged drug information 51 to the external distinction number information acquisition unit 44 and the mix determination possibility determination unit 47, respectively.

  As illustrated in FIG. 12, the drug appearance DB 43 stores a drug type of each drug 25 and drug appearance information indicating the drug appearance in association with each other. The drug appearance information includes the size (area, diameter, major axis and / or minor axis length, etc.), shape (circular, triangular, elliptical, capsule shape, etc.), color (for example, RGB value) of the drug 25. , Information indicating an identification code (number, alphabet, katakana, etc.) is included. It should be noted that L1, L2, L3, L4,... Indicating the size of each medicine A, B, C, D,..., S1, S2, S3, S4,. , C1, C2, C3, C4,..., ID1, ID2, ID3, ID4,.

  The appearance distinction number information acquisition unit 44 refers to the drug appearance DB 43 based on the packaged drug information 51 input from the packaged drug information acquisition unit 50, and stores each of the drugs 25 packaged in each packing bag 27. Appearance distinction number information 53 indicating the number of appearances (appearance distinction number) is acquired. For example, when the packaged medicine information 51 corresponding to the packaging bag 27 of “Packaging 1” is “A × 1, B × 1, C × 1”, the distinctive appearance number information acquisition unit 44 With reference to the drug appearance information corresponding to the drugs A, B, and C in the appearance DB 43, the appearance distinction number information 53 of “Package 1” is determined. In this case, the appearance distinction number information 53 of “Package 1” is “(L1: S1: C1: ID1) × 1, (L2: S2: C2: ID2) × 1, (L3: S3: C3: ID3). ) × 1) ”. As a result, the appearance of (L1: S1: C1: ID1), (L2: S2: C2: ID2), (L3: S3: C3: ID3) "is satisfied in each of the sachets 27 of the sachet 1. It can be seen that one medicine 25 is contained.

  In the same manner, the distinctive appearance number information acquisition unit 44 determines the distinctive appearance number information 53 corresponding to the packaging bag 27 of “Packaging 2, Packaging 3,...”. Then, the individual appearance number information acquisition unit 44 outputs the individual appearance number information 53 of each packaging bag 27 to the individual appearance number correct / incorrect acquisition unit 46. In the present embodiment, the distinctive appearance number information acquisition unit 44 acquires the distinctive appearance number information 53 based on the packaged drug information 51 acquired from the packaged drug information acquisition unit 50, but the packaged drug information acquisition unit 50 functions may be provided to the external distinction number information acquisition unit 44. That is, without providing the packaged drug information acquisition unit 50, the distinctive appearance number information acquisition unit 44 refers to the drug information DB 41 based on the dispensing information 22 and the drug type information 37 acquired from the input drug type correctness determination unit 42 and the like. The packaged medicine information 51 may be acquired. Thereby, the distinctive appearance number information acquisition unit 44 can acquire distinctive appearance number information 53 based on at least the dispensing information 22 and the drug type information 37.

  The appearance-specific counting unit 45 analyzes the image data of the medicine 25 of each pre-packaging (packaging 1, packaging 2,...) Input from the fourth camera 32, It is possible to count the number of distinct external appearances of the medicines 25 that are individually packaged in the wrapping bag 27. In the present embodiment, the medicine 25 of each 1-packaging (packaging 1, packaging 2,...) After the packaging input from the imaging unit 60 (the first camera 60A and the second camera 60B). The image data is analyzed, and the number of distinct external appearances of the medicine 25 packaged in each packaging bag 27 is counted. In the present embodiment, before the image data of the medicine 25 for each one-packaging (packaging 1, packaging 2,...) After the packaging is obtained by the first camera 60A and the second camera 60B. In addition, by driving the dispersion mechanism 70, the medicine 25 in the sachet 27 for each one sachet can be spread. By spreading the dispersion mechanism 70, the medicine 25 in the sachet 27 can be accurately imaged.

  Before driving the dispersion mechanism 70, the first camera 60A and the second camera 60B acquire the image data of the medicine 25 for each sachet after the sachet, and determine whether or not to drive the dispersion mechanism 70. It can also be judged.

  In FIG. 12, the fourth camera 32 and the imaging unit 60 are shown. However, by inputting at least image data from the imaging unit 60, it is possible to audit the medicine 25 after packaging.

  Specifically, the appearance-specific counting unit 45 performs known edge extraction processing and segmentation processing on the image data, and extracts the outline of the medicine 25 in the image, whereby the size and shape of the medicine 25 in the image are extracted. Can be determined. Further, when the image data is color image data, the appearance counting unit 45 can determine the color of the medicine 25 in the image based on the image data. The appearance counting unit 45 can determine the identification code of the medicine 25 in the image based on the image data when the image data includes the identification code. Note that the method of counting the number of distinct external appearances of the medicine 25 based on the image data is not particularly limited, and various known methods may be used. The external appearance counting unit 45 outputs the external distinction number actual measurement information (hereinafter simply referred to as actual measurement information) 55 indicating the count of the external distinction number to the external appearance number correct / incorrect acquisition unit 46.

  The identification code means a character or pictograph that is stamped or printed on a tablet, capsule or the like for the purpose of identification.

  The actual measurement information 55 is basically in the same format as the above-described distinct number-of-appearance information 53, and the actual measurement information 55 includes a count result “appearance 1 (size, shape, color, identification code) for each package. ) × number, appearance 2 (size, shape, color, identification code) × number,.

  The appearance distinction number correct / incorrect acquisition unit 46 collates the appearance distinction number information 53 input from the appearance distinction number information acquisition unit 44 with the actual measurement information 55 input from the appearance counting unit 45. Then, the appearance distinction number correct / incorrect acquisition unit 46 determines whether or not the appearance distinction number of the medicine 25 packaged in each packaging bag 27 is correct based on whether or not the actual measurement information 55 matches the appearance distinction number information 53. The determination result J2 is output to the package correctness determination unit 48. At this time, if the number of distinct appearances of the medicine 25 put in the packaging bag 27 is incorrect, the distinctive appearance number correct / incorrect acquisition unit 46 displays the determination result J2 including information indicating the corresponding packaging bag 27. The data is output to the package correctness determination unit 48.

  As illustrated in FIG. 13, the mixability determination possibility determination unit 47 refers to the drug appearance DB 43 based on the packaged drug information 51 input from the packaged drug information acquisition unit 50, and determines whether or not the drug 25 is mixed It is determined whether or not can be determined.

  As illustrated in FIG. 13, the mixability determination possibility determination unit 47 refers to the drug appearance DB 43 based on the packaged drug information 51 input from the packaged drug information acquisition unit 50, and determines whether or not the drug 25 is mixed Mistake possibility information 58 indicating whether or not can be determined is acquired. Specifically, the mixability determination possibility determination unit 47 refers to the drug appearance DB 43 based on the packaged drug information 51 and acquires drug appearance information corresponding to each drug 25 in the packaged drug information 51. In the “packaging” column of the confusing possibility information 58, information indicating which packaging bag 27 (packaging 1, packaging 2,...) Is loaded with the medicine 25 is stored. .

  Subsequently, the mix-up determination possibility determination unit 47 determines based on the mix-up possibility information 58 whether or not it is possible to determine whether or not the medicines 25 packaged in the respective packaging bags 27 are mixed up. Specifically, the misunderstanding determination possibility determination unit 47 determines that the appearances of different types of medicines 25 (medical agents 25 having different types between the packaging bags) that are put into the different packaging bags 27 from the following first condition: It is determined whether or not the fourth condition is satisfied. Note that the number of these conditions increases or decreases according to the number of parameters (size, shape, color, identification code) of the number of distinct appearances.

  The first condition is that the difference in the shape of the aforementioned different types of medicines 25 is small. For example, the mix-up determination possibility determination unit 47 determines whether the difference between the drugs is less than 0.1 mm when the shape of another type of drug 25 is expressed by the difference between the diameters of the circumscribed circle and the inscribed circle, or the shape is circumscribed. When the difference between the medicines expressed by the maximum distance between the outer edge and the outer edge is less than 0.1 mm, it is determined that the difference in the shape of the different kinds of medicines 25 is small.
